FunFam 52748: Alpha-amylase (1,4-alpha-D-glucan glucanohydrolase...

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Alpha-amylase. [EC: 3.2.1.1]
Endohydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides containing three or more (1->4)-alpha-linked D-glucose units.
  • Acts on starch, glycogen and related polysaccharides and oligosaccharides in a random manner; reducing groups are liberated in the alpha-configuration.
  • The term 'alpha' relates to the initial anomeric configuration of the free sugar group released and not to the configuration of the linkage hydrolyzed.

Glucan 1,4-alpha-maltohexaosidase. [EC: 3.2.1.98]
Hydrolysis of (1->4)-alpha-D-glucosidic linkages in amylaceous polysaccharides, to remove successive maltohexaose residues from the non- reducing chain ends.
  • Cf. EC 3.2.1.3, which removes successive glucose residues.
  • Cf. EC 3.2.1.2, which removes successive maltose residues.
  • Cf. EC 3.2.1.116, which removes successive maltotriose residues.
  • Cf. EC 3.2.1.60, which removes successive maltotetraose residues.
  • The products have the alpha-configuration.
